Title:
POWER TRANSMISSION DEVICE AND IMAGE FORMING DEVICE
Document Type and Number:
Japanese Patent JP3422666
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent producing an abnormal sound by absorbing the vibration of a rotational transmission system caused by the fluctuation of a load applied on a driven gear.
SOLUTION: A driving gear 35, a freely flexible damper member 49 and the driven gear 36 are coaxially arranged, the driving force of the driving gear 35 is transmitted to the damper member 49 by the engagement of protrusions 52 formed on the driving gear 35 with locking holes 55 formed in the damper member 49 and the driving force after being received by the damper member 49 is transmitted to the driven gear 36 by the engagement of the locking holes 55 of the damper member 49 with protrusions 54 formed on the driven gear 36. Further, the vibration of the rotational transmission system caused by the fluctuation of the load applied on the driven gear 36 is absorbed by the flexible work of the damper member 49, to prevent producing an abnormal sound.
